이동 위성 통신 시스템에서 패킷 전송을 위한 다원 접속 프로토콜

초록

In moblie communication systems using satellite, various multiple access protocols are used to provide service in packet switching networks between mobile stations, or between mobile stations and fixed stations. Mobile stations contain airplanes, ships, cars and persons. Fixed stations contain gateway stations of conventional PSTN, base stations of cellular mobile communication systems and control centers of managing satellite communication networks. To efficiently provide such various types of users, a nnew multiple protocol using satellite is needed. Since reservation multiple access protocols and random multiple access protocols which are currently employed in most satellite systems have some strength and some weekness, a new multiple access protocol with better characteristics is needed to improve the quality of service. In this paper, a protocol with better performance than conventional protocol is proposed. Using simulation and frame structure, and make a comparison between protocols in the same enviroments.
